CHARLES o.

--Bef'it 'known that'I, CHARLES Hays, 'a 'citizenof the-United States, resi-ding at Locust; Corner, in the county o f Clermont and 5 State of Ohio, have invented certain new and useful Improvements in Phono' ;ra-phs` l ing mechanism of a .15 'mechanism of any of which. the following is aspecification.

. The invention relates to the combination of a mandrel mechanism with the operatdisk-record phonograph, to the effect that the mandrel mechamsm of 'any-ordinary type of.. phonograph 'foi'. the use of cylinder records can Abe 4used in 'connection with the cabineta'nd operating ordinary type of diskrecord phonograph.. This general object -is accomplished bymounting thel mand-rel mechanism on a' suitable frame adapted v.to

' lrest 0nA the cabinet of the disk machine around the turn table thereof, and by gearin the cabinet is provided the usual mot0r ing with the mandrel mechanism a friction Wheeladapted to travel on-the turn table and to be rotated by the same to actuate the mandrel mechanism.

The invention, thus set forth in. general "terms,l is illust-rated in the accompanyingl drawings, forming part hereof, in which- Figure 1 is av perspective view showing a mandrel mechanism mounted on the cabinet of a disk-record phonograph; Fig. 2, an end elevation of the same; Fig. 3, a front elevationof part of same; Fig. 4;, a fragmentary section on line 4.-4, Fig. 2; and Fig. 5, a detached perspective View of the ,compen- 5 sating levers.

-Similar numerals refer to similar parts throughout the drawings. On the cabinet 1 of the disk-record phonograph is mounted the usual turn table 2, and

and other operating mechanism (not shovvn) for rotating the turn table', the same being provided with t-he usual brake and regulator 3. The tone arm l and the horn 5 are l5,mounted onA the bracket 6 which in turn is 1 4 formed or secured on the standard 8,

ysecured to the cabinet in the usual manner. The mandrel mechanism includes' the usual base plate '.7, the standards 8 and 8?' thereon, the mandrel 9 having .its shaft 10 jour- Vnaled in the standard S, the gear wheel 11 ing gear Wheel 12 secured on the driving shaft 13 which is journaled in the bearing 'qvhch-driving gear Wheel meshef. with the `f PHoNoGRAPH.

mandrel-wheel 1l on one side and feed gear Wheel 15 on t-he otherside; and on the outer end of the driving shaft is secured the pullev Wheel 1G. l u The base plate?v of the mandrel mechapreferably secured to the cross bars 17 which in turn' are secured to "the'rectangular frame 18 which is adapted'to rest on the top of the disk-cabinet free-ly around the'turn table thereo and in this relation of the parts the cross bars 17 and thebase plate of the mandrel mechanismy arellocated freely above the turn table." 'IheosciHating arm 19 is pivoted at one end on the bearing 14 of the driving shaft .13, between and thepulley wheel 1G, and 1s plvoted at the other end to the angle of the L-lever 20, Whichvlever has its l'iorizontal arm plvoted to thel upperlend'ofvthe upright link 21, the loiver end of which link ispivoted to mechanism.

On the lower end of the depending arm of the L-lever 20 is provided the bearing 22 in which is mounted theaxle 23 of the friction -Wheel 24 which is providedwith the rubber or frictional tire or periphery 24a; and on the side of t-he friction Wheel is secured the pulley wheel 25. The belt or band 26 is provided around the pulley wheels. The U-shaped rod 27 is pivoted by its yoke 28 on the oscillating arm 19, on one end of which rod is pivoted the idle Wheel 29 and the other Aend of the rod is connected to the arm 19 by means of the spring 30.

lVhen the vmandrel mechanism, with its 'Patented Aug. i 1,911.

the base plate of the mandrel supporting frame, is placed upon the diskcabinet, the parts are so arrangedl that the periphery of the friction Wheel will rest upon the turn table' 2, preferably near the periphery thereof, and be rotated by the frictional contact therewith when the turn table is rotated by its operating mechanism;

and it is .evident that the oscillating arm 19, the L-lever 420 and the vupright link 21, which collectively-'may be called the compensating levers, will permit the friction Wheel to rise andl fall to conform to the. variations in the height of the turn table as it rotates, and it is evident that bythe peculiar 4arrangement of the `compensating levers,

that the friction Wheel'will rise and fall -in a substantially vertical line, so that it will neither advance nor retard with reference to the rotation of the disk; it is furthermore evident` that the action of the spring 30 serves to'press the idle Wheel 29 firmly against the belt 26 at all times, and that as thefriction iifheel is slightly elevated thel idle Wheel will press the b elt downward to keep it tightly around tliepulley wheels. And it will be understood that When-the mandrel mechanism is combined with the disk-cabinet, a. suitable connecting pipe as 3l is provided to connect the gooseneck 32 of the reproducer frame 33 With the tone arm, there being a rotatable sliding joint at Bet between the connecting pipe and the Gooseneck, and a swivel jointat .35 in the gooseneck, so that the phonograph is thus adapted for the use of cylinder records; and that when the mandrel mechanism and cor responding parts are removed, a. suitable dislr-reproducer (not shown) is secured tov the'tone arm', thus adapting the phonograph:

- for the use of disk lrecords mounted on the Aframe adapted to rest on-the'cabinet around the turn table, a. mandrel mechanism 'on the iframe, and a friction Wheel 'resting on the` frame adapted to vrest on the cabinet around- ,the turntable, a mandrel mechanism on the.

frame, a frictionwvheel'resting on the turn table and having a gearing connection with 'the mandrel mechanism, and a bearing for the friction Wheel connected with the an- -drel mechanism, whereby1 the Wheel is adapted to oscillate with the turntable.

3. The combination of4 a phonograph. eabinet 4having a rotatable tarn table thereon, a

frame adapted to rest' on the cabinet around the turn table, a mandrel mechanism on the frame, a friction ii'heel resting onthe turnA table and-having a gearing connection with the mandrel.- mechanism, and a bearing for lever connections with the mandrel menanism, whereby the pulley wheel is 'ada ted the friction Wheel having compensaglng to oscillate directly up and down Withlthe turn table.
